Which explains upwelling in the oceans?
a. coastal winds blow cold surface water out to sea. deeper, nutrient-rich, warm water flows upward to replace the surface water.
b. wind near the coastline blows warm surface water away from the land. deeper, nutrient-rich, cold water flows upward to replace the surface water.
c. solar heating near the coastline heats cold surface water, which diffuses out to sea. deeper, nutrient-rich, warm water flows upward to replace the surface water.
d. solar heating near the coastline heats warm surface water, which diffuses out to sea. deeper, nutrient-rich, cold water flows upward to replace the surface water.

The “twelve apostles” are in which national park?

If you could drill a hole straight to the center of the earth, and keep track of what the hole is going through, youwould find: a) you would go through one sort of material, and then a different, denser material, and then a still-different, still-denser material, because the planet is made of concentric layers, sort of like an onion. b) you would go through one sort of material all the way to the center, because the planet is all mixed up. c) if your hole started at the north pole, you would go through different layers of different materials, but ifyour hole started at the equator, you would go through one sort of material all the way to the center. d) if your hole started at the equator, you would go through different layers of different materials, but if yourhole started at the north pole, you would go through one sort of material all the way to the center. e) you would strike diet pepsi when you got to the center.
